Multiple Parameterized Filters
Differing filter match conditions can be achieved by allowing the filter that is being attached to be selected by the unique-identifier--reference capabilities of parameterized filters. If a variable number of terms or varying match conditions are needed, multiple filters are defined. When the service is activated, that activation will select the particular filter that should be applied in the stanza specifying the interface, unit, family and input/output filter:
interfaces { ge-1/0/0 { unit 7 { family inet { filter { input my-filt-1gw-uid1022; } } } } }
